WINDER.

Application filed December 4, 1919, Serial No. 342,407. Renewed May 7, 1923.

T 0 all whom it may concern.

Be it known that I. HOWARD D. COLMAN, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Winders, of which the following is a specification.

This invention relates to winders of the class shown in Patent No. 1,267,977, dated May 28, 1918, and comprising a traveling mechanism having means whereby power is shut off from the mechanism when the latter meets with an obstruction.

Oiie of the objects of this invention is to arrange the power-transmitting means so that it shall be operable by one of a plurality of devices for'dete'ctin'g the presence of obstructions.

Another object is to provide-means for detecting the presence of a misplaced bobbin or other article lying in the path ofthe de vice that operates the bobbin-holders In the accompanying drawings, Figure 1 is a fragmental front elevation of a winder embodying the features of my invention. Fig. 2 is a fragmental transverse sectional view. Fig. 3 is a detail view of a latch 1ever. Fig. 4 is a fragmental perspective view. Figs. 5 and 6 are views of one of the detecting devices, Fig.6 being a section on line 66 of Fig. 5. a

Reference may be had to the before-mentioned Patent No. 1,267,977 and to an application Serial No. 842214, filed December 3, 1919, by Burt A. Peterson for a disclosure of a winderto which this invention may be applied.

Referringnow to Fig. 2 of the present drawings, 6 denotes a tubular core on which yarn is wound to form a cheese 0. The core is removably mounted upon a suitable support, as, for example, a hub 30 such as the one shown in my application Serial No. 74,290 filed January 26, 1916 (now Patent No. 1,329,504, dated February 3, 1920). The hub is provided with means for locking the core in proper position 011 the hub. The hub is carried by an arm 30 which is pivoted at 31. The winder consists of a series of winding units, each of which includes an arm 30. To economize space, the winding units are arranged relatively close'together.

A carriage 88 is arranged to travel along the winder. To one endofjhe carriage 88 is attached a framework 89 which supports mechanisms that operate upon the winding units. The carriage is provided with rolle'rs, only two of which (90, 91) are herein shown. The rollers 90 and 91 run upon rails 86 and 92, respectively. The carriage 88 is caused to travel by means of a pinion (not shown) meshing with a rack 94. Power to actuate the mechanismswhich are mounted on the framework 89, and to rotate the aforesaid pinion is transmitted through a pulley 205 rotatably mounted on a shaft 206. The pulley is arranged to be connected to the shaft by means of a friction clutch member 209'fiXed upon a sleeve 210. Said sleeve is slidable'along the shaft 206, but the shaft is connected to rotate with the sleeve by means of a spline 2.10 (Fig. 2). An expansion spring 211 surrounding the shaft 206 is interposed between the shoulder 212 on said shaft and a flange 213 on the end of the sleeve 210, said spring normally holding the clutch member 209 in engagement with the pulley 205. The clutch member may be withdrawn from engagement with the pulley by means of a contractile spring 216 which is connected to an arm 214 of a hand lever 214. Said hand lever is mounted to swing on the axis 704. Rigid with the hahd lever 214 is an arm 214* which lies in contact with a pin 702 carried by a fork 703. Said fork is pivoted on the axis 704, and carries two studs 705 that lie at the side of the flange 213 opposite to that engaged by the expansion spring 211; The hand lever is normally held against actuation by the spring 216 by means'of a latch arm 657 fixedupon a rock shaft 658. The hand lever 214 hasa pro jection 659 (Fig. 3) which normally lies against a locking shoulder 660 on the latch arm. Below the shoulder 660 is a shoulder 661.

It will be seen that when the latch arm 657 is swung upwardly, the spring 216 is released to action and immediately throws out the clutch against the pressure of the spring 211.

Mounted on the framework 89 is means for promptly throwing out any cheeses that may be in running position when reached by the traveling mechanism. and for positioning successive cheeses with relation to the endfinder (not shown). This means comprises a throw-out plow 249 and a plow 250 located in position to lift the throw-out cheese arms 80 onto a horizontal surface or dwell 251. Rearwardly of the dwell 251 is an incline 252 which lifts the cheese arms onto the dwell 253.

Referring to Fig. 2: If a cheese 0 be disengaged from the latch of the hub on which it is mounted, said cheese may be so far out on its hub as to foul upon an adjacent thrown-out arm. 30, or such an unlatched cheese may prevent the adjacent cheese arm, when thrown out, from descending to its intended position. In order to throw out the clutch member 209 in the event of such a condition arising, I provide aplate or feeler member 267 rigidly attached to two arms 268 which are fixed upon a rock shaft 269. Onecdge of the plate 267 is of such outline as to define, in conjunction with the surfaces 251, 252 and 253, a passageway of sufficient width to admit a single cheese arm 30. If the traveling mechanism reaches a cheese arm which has been unable to descend to proper position, the inclined forward edge 274 of the plate 267 rides up on said cheese arm whereby the plate is lifted. Rigid with the plate 267 is cam flange 267 arranged to engage on arm 658 on the rock shaft 658. iVhen the plate 267 is lifted by an improperly-positioned cheese arm, the shaft 658 is turned in the direction to lift the latch arm 657, whereby the lever 214 is released and the spring 216 permitted to throw out the clutch member 209.

The plate 267 is yieldingly held innormal position by gravity.

A cheese may happen to fall into the space behind the series of brackets 48 disclosed in Patent No. 1,267,977., or the operator may lay some article in said space. To throw out the clutch member 209 in the event that the mechanism meets some such obstruction, I provide a feeder or plate 527 of suitable shape to travel through said space without unnecessary clearance. The upper part 527 of said plate is shaped so as to be interfered with by a broken antibounder spring or other broken part that may project into the path of the portion 527*. The plate 527 is attached to a slide 750 which is mounted in a guiding structure 751. The forward portion of the slide 750 rests upon a roller 752, while the rear end of the slide is provided with rollers 753 which move in guideways in the structure 751. A stop pin 754 (Fig. 5) in one of said ways serves to limit forward movement of the slide. Fixed to the slide is a plate 755 having a shoulder 756 which engages an arm 757, said arm being attached to a rock shaft 758. A torsion spring 759 surrounding the shaft 758 normally holds the feeler or plate 527 in its forward position. Rigid with the shaft 758 is an arm 760 to which is pivoted the lower end of a link 761. In the upper end of the link is a slot 762, in

which lies a pin 7 63 on a projection 764 on the latch arm 657. It will be evident that if the plate 527 collides with an obstruction, the arm 757 will be turned against the torsion of the spring 57 9,, thus causing the locking shoulder 660 on the latch arm 657 to be disengaged from the projection 659 on the clutch-operating lever 214.

Means is provided for detecting a misplaced bobbin or other article in the path of the device that operates the bobbin-holders. While I have herein indicated a bobbin-holder of the type disclosed in an application Serial No. 323,194, filed September 11, 1919, by Burt A. Peterson, it will be understood that the present invention is not limited to any particular type of bobbinholder. In Fig. 2 is! shown a portion of the casing 00 of a bobbin-holder, and the plunger y by means of which the bobbinholder is actuated to don the spent bobbin and place the reserve bobbin in running position. A cam bar 677 is attached to the framework 89 in position to extend longitudinally of the series of bobbin-holders and operate the plungers y in succession.

A feeler arm 7 65 is fixed toand extends downwardly from the rock shaft 758. 7 65 is a stop to limit the movement of the feeler arm under the action of the spring 759. The lower end of the arm 7 65 is bifurcated to straddle the cam bar 677 and the series of plungers y The arm 765 is located near the forward end of the cam bar 677 so as to be engaged by a bobbin projecting from or lying upon a bobbin-holder or by any other obstruction which would interfere with the travel or operation of the cam bar 67 7 Upon striking an obstruction, the arm 7 65, which is rigid with the arm 760, will cause the latch arm 657 to be disengaged from the clutch-operating lever 214.

It will be observed that all of the feelers 267, 527 and 7 65 are arranged to operate a single means for throwing out the clutch to stop the travel of the carriage 88 and suspend operation of the winder-tending mechanism carried by the framework 89.

The shoulder 661 on the latch arm 657 prevents the hand lever 214 from being returned to running position until the latch arm has been lowered, and this latter cannot be effected until the obstruction which caused stoppage has been removed.

The slot 762 permitsthe latch arm 657 to be manually raised at will without the necessity of overcoming the torsion of the spring 7 59. and also relieves the plate 267 of the resistance of said spring.
